Fujitsu U7511 E5511 Imaging Deploy

[Francois]

Hello, I’m a long time FOG server user, and first of all you do an amazing job !

I’m imaging on Fujitsu computers (esprimo P558/P5010 Q558/Q7010) and laptops (lifebook A359/A3510 E559/E5510 U759/U7510) for around 3 years now.
When I had difficulties with new generation (last 1/2 digits on product number 9/10 eq. 9/10th gen intel core proc) I used to update Kernels and iPxE and it just works.

However I have an issue deploying image on last generation Fujitsu laptops (E5511 and U7511).
FOG v1.5.9
Kernels v5.10.71
iPxE v1.21.1 [g1192e]
I have a workaround, using a USB-network adapter and it works just fine booing and imathing through this ethernet interface ipv4. Atolla adapter on Amazon.fr
When I try booting my laptop on the native ethernet interface ipv4, it successfuly loads up to FOG main menu then [deploy image] then it take ages to restore image [here is a picture i took during the process]

@francois Have you checked to see if you have the latest firmware on these troubled Fujitsu computers?

I agree that 944 KB/min is terrible. Who has time for that? (joke).

I would first start by making sure firmware is up to date. Then we can debug more to see if its network or slow disk making imaging slow for you.

This points to the Linux kernel driver not having an issue on this paticular device/network card or a firmware issue as George pointed out.

As there is a new long term branch for the Linux kernel I just compiled a fresh 5.15.19 kernel. You are welcome to test it: https://github.com/FOGProject/fos/releases/download/testing/bzImage-5.15.19

@sebastian-roth i’m going to start with this, thank you.

@george1421 If the kernel update doesn’t work i’ll give it a try, thank you too.

[Francois]

@sebastian-roth It worked, Thank you very much !
@george1421 It’s way better now, anything GB/min is far more desirable !

Thank you both of you, it’s solved.
If anyone ever has the same issue [FUJITSU E5511 U7511 deploy image is super slow], here is what i did :

• Download bzImage-5.15.19
• Move it to /var/www/html/fog/service/ipxe/
• On your FOG server web page go to [FOG Configuration] top menu > [FOG Settings] on the left pane > expand [TFTP Server] > replace [TFTP PXE KERNEL] item by bzImage-5.15.19
• It should work now
  When the [Kernel Update] item on the left pane will be updated with new version you will have to change back [TFTP PXE KERNEL] item to bzImage

@francois Very good speeds. I would say you are running parts of your network on 10GbE on a healthy network to get those deployment speeds. Well done!.

I am surprised that 5.10.71 was giving you those bad speeds where 5.15.x is working. Surprised in this case is a good thing.

@george1421 I isolated my production network from my Deployment network.
If you’re interested, here is a logical network plan of my FOG Network

• “Switch FOG” is an old D-Link DGS-1016D
• I also used D-Link DGS-1024D [with “Port isolation & Storm control switch” turned ON that comute only the 24th port with the others] when i mass deployed using multicast 24 laptops per deployment (last picture is 100% show off)

@francois Very nice setup!!

[Sebastian Roth]

@Francois Great!! I am surprised just as much as @george1421 is. While I did hope the newer kernel version might help it was more of a straw I pulled at. Anyhow, great this worked for you and thanks a lot for your quick response. This is a good starting point for us to move on and make the 5.15.x kernel series the new default. I just started a full build. New official (dev) kernel version will be available here soon: https://github.com/FOGProject/fos/releases

@sebastian-roth I had to hand over the U7511 and i did test on another laptop [E5511] ; i’m going to test on another U7511 when i’ll receive a new one next week. I’ll get you in touch.

Thank you again for the good work you do !
